A study was carried out to determine the type of bacteria
associated with bovine dermatophilosis in Zaria, Nigeria.
Skin samples obtained from two hundred and eleven cattle
with skin lesions suspected to be dermatophilosis were
processed for bacteriology. One hundred and sixty-seven
(79.1%) samples were positive for Dermatophilus
congolensis, while 44 (20.9%) were negative. Both D.
congolensis-positive and D. congolensis-negative
samples were processed for isolation of other bacteria and
the data was analyzed using Chi square test.
Staphylococcus aureus, Staphylococcus epidermidis,
Bacillus subtilis, Micrococcus spp.,
Corynebacterium spp., Escherichia coli,
Proteus spp. and Pseudomonas spp. were
isolated from both D. congolensis-positive and D.
congolensis-negative scabs. However, the rate of
recovery of S. aureus from D. congolensis-positive
cattle was significantly (P < 0.05) higher than the rate of
its recovery from D. congolensis negative cattle.
There was no significant difference (P > 0.05) between the
occurrence of the other isolates in D. congolensis-
positive and D. congolensis-negative cattle. It was
concluded that S. aureus could be a major
complicating factor in naturally occurring dermatophilosis
of cattle. The need to investigate the role of bacteria
particularly that of S. aureus in the development of
bovine dermatophilosis was emphasized.

bacteria, Zaria, Nigeria.
